TECHNICAL FIELD

The utility model concerns a gel mat and its UV solidification production method.

BACKGROUND ART

For recent years, some cool mats (e.g. application No.: 200810063081.4) as gel mat were put into market. However, they are troubled with insufficient cool duration and unremarkable cool sense. In addition, during production of the products, surface of the product is with long “concave”; the content is easily spattered on to outer package material causing dirty for the surface of the product; in case of uncompleted air expelled from the pack during sealing, there will be plenty of “concaves” on surface of the product, and thus makes the product ugly by appearance; the production process needs thermal pressure, and therefore costs much energy; when the product is produced, it can not be packaged until cooled. Thus, it is with the shortcoming of complicated production process and large area needed for the factory.

Moreover, theses methods in production need long term for heating solidification, costs plenty of energy and achieves a low efficiency (e.g. application No.: 200810063081.4). Some of the methods cost less energy, but over 5 hours are required for solidification and thus seriously lowered production efficiency and operation; in addition, some gel mats formed with macromolecule cross-linking are troubled with serious problems like insufficient intensity, short lifespan of colloid and easily distortion caused, and insufficient solidification.
